Brown midrib sorghum for second-generation ethanol production. Abstract
No full textSorghum[Sorghum bicolor (L.) Moench] stover can provide an abundant alternative source of fermentable sugars through enzymatic hydrolysis (Vermerris et al., 2007). While production of cellulosic ethanol from stover is feasible from an energy-balance perspective, its production is currently not economically viable. Improvements in bio-processing, technologies coupled with development of high biomass yielding genotypes with low lignin content make ethanol production cost effective. The brown midrib (bmr) mutant sorghum lines have significantly lower levels of lignin content (51% less in stems and 25% less in leaves (Porter et al., 1978). Therefore, the use of bmr cultivars would reduce the cost of biomass-based ethanol production by reducing pre-processing costs. ICRISAT has developed 11 female parents (A-/B- lines) and 22 pollen parents (R-lines) using bmr 1, bmr 3 and bmr 7 sources for development of high biomass bmr sorghum hybrids (Reddy et al., 2008). Preliminary evaluation of bmr hybrid parents (4 R-lines) derived from bmr 1 source (IS 21887) indicated 20% lower lignin content on whole plant basis compared to source (4.24%). Further, two brown midrib sources bmr 6 (reduced activity of cinnamyl alcohol dehydrogenase) and bmr 12 (reduced activity of caffeic acid O-methyl transferase) are under use in breeding program for bmr introgression. With several bmr mutant sources available in gene bank, ICRISAT has a comparative advantage to develop high biomassyielding bmr sorghum hybrids for enhancing ethanol production from stover

P.S.: Further Thoughts from a Lifetime of Listening
No full textThe pieces in P.S. reflect Studs’s wide-ranging interests and travels, as well as his abiding connection to his hometown, Chicago. Here we have a fascinating conversation with James Baldwin, possibly Studs’s finest interview with an author; pieces on the colorful history and culture of Chicago; vivid portraits of Studs’s heroes and cohorts (including an insightful and still timely interview with songwriter Yip Harburg, known for his “Brother, Can You Spare a Dime”); and the transcript of Studs’s famous broadcast on the Depression, the very moving essence of what was to become Hard Times.https://corescholar.libraries.wright.edu/dlpp_all/1204/thumbnail.jp
Minding the gap between policy and practice amongst extension workers : lessons from KwaZulu Natal
Get PDFCITATION: Mohamed Sayeed, C.N., Reddy, P.S. & Pillay, P. 2015. Minding the gap between policy and practice amongst extension workers: Lessons from KwaZulu Natal. South African Journal of Agricultural Extension, 43(1):57-65.The original publication is available from http://www.scielo.org.za20 years into a post-apartheid South Africa, the National Development Plan (NDP) provides the contextual and institutional framework for all of governments activities. As a result, there is a call for extension to increasingly become associated with efficient and effective delivery of services in line with government policy to improve the quality of public services which are critical to achieving a transformed racially equitable public service. This article interrogates the issue of a gap between policy and implementation amongst Extension Workers by reflecting on the findings of research conducted as part of a doctoral study in Public Administration by the main author at the University of KwaZulu Natal. The article makes reference to the findings related to policy knowledge amongst Extension Workers and the challenges related to policy implementation in KwaZulu Natal, and seeks to use the findings of this research to present opportunities and challenges for the implementation of the NDP and concludes that whilst Extension Workers are now challenged to find a balance between their functionality within extension and as public servants, it is important for some consideration to be made by government and education institutions for the changing roles of Extension Workers.http://www.scielo.org.za/scielo.php?script=sci_abstract&pid=S0301-603X2015000100006&lng=en&nrm=iso&tlng=enPublisher's versio
Organic Farming: Status, Issues and Prospects – A Review
Get PDFThis review paper attempts to bring together different issues in the light of recent developments in organic farming. The after effects of green revolution have encouraged the farmers to take up organic farming. This paper has reviewed the global and Indian scenario with reference to organic farming. In India, the cultivated land under certification is 2.8 Mha only. The key issues emerging in organic farming include yield reduction in conversion to organic farm, soil fertility enhancement, integration of livestock, certification constraints, ecology, marketing and policy support. The potential for organic farming, especially in the dryland regions has been discussed. It has been argued that organic farming is productive and sustainable, but there is a need for strong support to it in the form of subsidies, agricultural extension services and research.Agricultural and Food Policy,
